New printing technologies for stamps

In 2022, the Postal Service released several stamps that highlighted stamp printing technologies.

• The Lunar New Year — Year of the Tiger stamp, part of the Celebrating Lunar New Year stamp series, had intricate gold and purple foil in the stamp artwork and selvage.
• Women Cryptologists of World War II featured a design that incorporated type written in code with a special cipher printed on the back of the stamp pane.
• Mountain Flora note cards were printed and embossed on matte paper to give the designs texture and dimension that resembled letter-press printing.
• The Music Icons: Pete Seeger stamp poster was screen printed in three colors and in limited quantities with the stamp affixed.
• The Charles M. Schulz stamp pane was featured in a letter-writing kit with self-mailing sheets of paper with stickers.
